Abstract

본 발명은 자막이 영상을 가리지 않도록 영상신호가 표시되지 않는 화면의 여백부분에 자막을 표시할 수 있는 영상표시장치에 관한 것으로, 4:3의 화면비로 화면출력할때는 기설정된 자막표시영역에 자막을 표시하는 반면에 16:9의 화면비로 화면출력시 형성되는 화면의 여백부분에 자막을 표시할 수 있도록 영상신호와 자막신호를 선택출력한다. 따라서 4:3의 화면비를 갖는 영상표시장치는 16:9의 화면비로 자막을 표시할 때 화면의 상ㆍ하단에 형성되는 여백부분에 자막을 표시할 수 있어서 시청자가 원활하게 시청할 수 있는 장점이 있나.The present invention relates to an image display apparatus capable of displaying a caption in the margin of a screen where a video signal is not displayed so that the caption does not block the image. On the other hand, the video signal and the caption signal are selectively outputted so that the caption can be displayed on the margin of the screen formed when the screen is output at the aspect ratio of 16: 9. Therefore, an image display device having an aspect ratio of 4: 3 can display subtitles in the margins formed at the top and bottom of the screen when displaying subtitles with an aspect ratio of 16: 9, so that viewers can watch smoothly. .
